We know Game Freak as the developer of Pokemon, as well as Quinty/Mendel Palace, which Arino played many episodes ago. But after Quinty, their first Super Famicom game was Jerry Boy. It was also known as SmartBall outside Japan, and in a rather neutered version, as well. SmartBall had little to none of the actualy story bits of Jerry Boy, so here, we get to see the whole hullabaloo of a young prince, Jerry, turned into a slime by an evil magician who also goes ahead and steals the princess. For Arino, this means he must complete all eight worlds in this cute platformer before midnight.
